H4 halogen or led in early Ford headlight

Have any of you installed an H4 halogen or led in an early Ford headlight? What did the beam pattern look like?

 

Any good manufacturer should probably include the output pattern.
If you mean how is it modified by the original lens, you might want to narrow the focus ( ) of the question.

Thanks, that's what I'm after. What do those bulb outputs look like behind an original lens and reflector.

 

I have Holley LED's in my 48 and it's been the best pattern of any of them I've tried.

 

Thanks. I've used those too and they are very good.
I'm just wondering what the pattern of something like a 32 or 34 Ford light looks like with a new bulb, especially the difference between high and low.

 

I’ve heard that halogens need reflectors shaped differently. Here are photos of a reflector in a ‘32 lamp-
The first one shows the raised area where the bulb is placed. The next two show a 180* segment that is raised about 1/4” at the bottom of the reflector, and that tapers to zero near the bulb, I’m guessing that has something to do with low and high beam. The lines show where the taper is and the arrow shows the 1/4” depth, and yes, it’s hard to explain and visualize. The point is, I don’t think an original style reflector works well, the focus of the light will be poor.

A,s & 32 The Reflector that were sold around 15 years a go to be used with
9004 or 9006 bulb? Like Vintique sold
Where bright , I felt beam pattern was wrong
Compared to Original restored OEM
Reflected, Model A's bulbs where adjustable Originally by moving the bulb in and out from the Flutes .

Bob Drake made a Reflector with a Raised Area where the Bulb mounts &
Was all chrome plastic Much better
Flute / Beam pattern then
Vintique ,
As far as I know B - D No longer makes in last 7 or so years .
I am surprised That Holley does not make There Versions for Pre war .

 

Yes, the Bob Drake reflector is described in the last two photos posted by @Fordors above.

The design works very well behind the original lens. I have used them on 33/34 commercial and 35-37 commercial Ford headlights.

Unfortunately, it appears that they are no longer being produced.

I'm not aware of an alternative that is comparable.

 

Thanks @19Eddy30 and @pprather , your posts helped explain what I was trying to say. I have a set of Drake’s ‘32 lights on the shelf (for too long) for my Fordor. And I didn’t know that they’ve been unavailable for years, mine were an eBay score.

 

That's what I meant by narrow the focus.
The lens and reflector (Year, Make, Model, OE or aftermarket) along with the bulb.

 

It would , I think Nice if some one
Made / stamped in a metal Version
Or One's with 3d printer make / print out ,,,
If I had & knew software writing I would be making all kind's of Old OEM
Like the 40/41 Buick Black Out tail lights
